Hi
When I load a flight plan, everything looks ok. The ins is aligned and set to nav, and works just fine. After TO I engage the auto flight system and auto throttle and the aircraft begins to follow the flight plan.
After a while the “heading ” light goes out, and the aircraft turn around and head  back in the opposite direction, and the  autoflight system can’t  be initialized again, This happens on all flights and I am out of ideas. Any help is welcome. The aircraft is one of the best looking in my hangar, and behaves basically really well, so I will hate to turn her into a hangar queen.

Kindly

Jakob
